Abstract
Objective: The correct positioning of lingual borders of mandibular denture is challenging. The border seal is achieved by the contact of borders with the soft tissue. However because of the tongue the lingual borders are not visible directly. The influence of so many muscles on the borders of the denture makes the understanding of lingual borders all the more complicated. Method: This article attempts to describe the clinical anatomy of the lingual vestibule and its influence on denture borders. Dissection of the floor of the mouth was carried out on cadaver through an intra oral approach and the anatomy described. Routine border molding and final impression procedure for the mandibular denture was carried out on a patient receiving complete dentures in the post graduate clinic in the department of Prosthodontics. Results and Conclusions: The anatomy observed on dissected cadaver section was co related to the shape of the borders developed during the clinical procedure of border molding and final impression.
Highlights
Achieving correct positioning of the lingual borders of the mandibular denture has taxed the abilities of generations of prosthodontists
The anatomy observed on dissected cadaver section was co related to the shape of the borders developed during the clinical procedure of border molding and final impression
Tilton further stated that “border molding ends at a point where the border tissues seat firmly but lightly against the denture periphery when the border tissues are in extreme function” [2]
Summary
The anatomy observed on dissected cadaver section was co related to the shape of the borders developed during the clinical procedure of border molding and final impression.
